Bird-a-thon, Mass Audubon’s largest fundraiser, brings together supporters from across the state to raise essential funds for nature conservation, education, and advocacy and to compete in an exciting birding competition.

Each year, over 20 teams compete to spot as many bird species as possible in a 24-hour period. Team members and other supporters raise money for Mass Audubon sanctuaries and programs in honor of their participation. 

The Bar is Set

Our goal for Bird-a-thon 2020 is to raise $250,000 for Mass Audubon's sanctuaries and programs.

Since this event began in 1983, thousands of dedicated Bird-a-thon supporters and team members have raised well over $3 million for Mass Audubon, its wildlife sanctuaries, and its programs statewide.

Join the Fun

→ Registration for Bird-a-thon 2020 will open on Tuesday, April 7. ←

Anyone can participate in Bird-a-thon by joining a team as an Official Birder or a Bird-a-thon Booster and help raise money for your favorite sanctuary or program!

An Official Birder’s species checklist counts towards their team’s total, while Bird-a-thon Boosters bird for fun, do their own nature-bases activity, or participate solely through fundraising. 


Our event planning team is currently looking for sponsors for Bird-a-thon 2020. Discover the benefits of becoming a Bird-a-thon sponsor >
